Note (
44
) The rated voltage of each phase and W phase is 100V. However, the full scale of a bar graph is 300V.
Note (
45
) If this unit directly measures an inverter output of cycle control, SCR phase angle control or PWM, an error
may increase due to its operation principle.
As for harmonic 5th conversion effective value and nth harmonic effective value, a display will be zero by
0.2％ or less of the measurement range. And, analog output constitutes lower limit output. At this time,
a distortion factor, harmonic 5th conversion content rate, and nth harmonic content also become 0％ (analog
output is lower limit output). As for a distortion factor, harmonic 5th conversion effective value / content,
and nth harmonic effective value / content, fundamental-wave effective value constitutes zero by 3％ or less
of the measurement range.
Note (
46
) Analog output and pulse output are options.
Analog output of harmonic distortion factor and harmonic content：It becomes an upper limit output from a lower
limit output, for current 0 to 100％ and voltage 0 to 20％.
The analog output of current leakage constitutes an upper limit output to leakage sensitivity current value.
(Only with leakage measurement)
Note (
47
) Single-phase 3-wire：UN-WN-UW, Single-phase 2-wire：With no phase display.
Note (
48
) Single-phase 3-wire：U-W-N, Single-phase 2-wire：With no phase display.
Note (
49
) At the case of one side swing setting of bar graph. Digital meter measures reverse power to -15% full scale.
(Instantaneous power)
Note (
50
) Active power, reactive power display digit.
A full scale display is below 4000：4 digits display. A full scale display is 4000 or more：3 digits display.
Example) 4800kW → 4.80MW
40kvar → 40.0kvar
20kW → 20.00kW Please refer to an appendix table for details.
Note (
51
) Only with leakage measurement. However, current input product constitute only Io method.
Note (
52
) The error of ZCT is not included. However, leakage detection sensitivity current below 0.1A constitutes
±0.0025A (ZCT primary).
Note (
53
) Single-phase 3-wire：UN-WN，single-phase 2-wire：With no phase display, line display.
Note (
54
) Single-phase 3-wire：U-W，single-phase 2-wire：With no phase display
Note (
55
) The maximum value (maximum demand current, others) minimum value can be checked in the maximum and the
minimum measurement mode.
